[Tutorial] How to make your 900 Series Video Card have a 0% fan mode!

[Tim89]

Hi There,

 

I have ordered a Gigabyte GTX 970 G1 Gaming card.

 

I am interested in using your technique to enable 0% fan mode.

 

My only question is - can you update your bios after this function has been enabled?

 

Thanks

 

Tim

I doubt you'd ever need to update your BIOS, as GPU's don't usually get "bios improvements" 

 

But if you did update it, you'd need to make these changes to the new BIOS before flashing it.

[Tim89]

Thanks Lays :-)

 Hi, I have a Gigabyte 970 G1 and done this bios mod. Does anyone else get random fan spikes? I happens sometimes after the fans ramp up and even on idle sometimes. Is there a fix for this or is it normal? Will this damage the fans? GPUZ also reads this insane RPM number.

 

 

The number is not always 810811RPM.

 

Thanks

I recently did it on my windforce (non G1) 970, not having any problems. What does your fan curve look like? Also, setting your hysteresis to ~5-10 might help in reducing fluctuations. No idea about the random spike, does it happen often?

[PremiumLight]

Fan curve is the same as the ones posted here. Hysterics set at 10c. Reading through this post is appears that others have a similar issue. It only happens randomly. Maybe once every 15min? I might try different bios values and see if it helps. I also read that spikes maybe due to drivers.

This is great bios mod though. Now my rig is silent.

[Imakuni]

I wonder why I bothered to do it, given the fact that my card is always on a high load.....

 

 

Oh well, I guess at least I don't need Afterburner to make a custom fan curve anymore.

I can confirm that this method works for my EVGA GTX 750 Ti SC (First-gen Maxwell, GM107). You just have to make a custom fan curve in MSI Afterburner and set the fan to the user-defined speed. However, this only seems to work when MSI Afterburner is on, otherwise, the fans will turn back on again back to their default curve once I close the application.

Yes because when afterburner isn't open, it will use the cards BIOS to define fan speed.

 

In theory you could go and edit every single value in the BIOS fan curve and do it yourself and not require afterburner to be open, but it'd take a lot longer & some trial and error.

Ahh, great, thanks! Awesome tutorial by the way too! (And Linus as well)

Anyone try this with a titan x yet?

Would probably not be a good idea to try it with a Titan X, as it has a much higher TDP, and a lesser cooler than aftermarket 970s/980s.

 

Since it's reference design, the airflow from the rest of the case doesn't really cool it as much as an open-air design.

I modded the GV-N970G1 BIOS after restarting and entering MSI AfterBurner, I set the fan lay out, to 0% till it hit 60c, this worked great, till I started to notice the fans would just move on there own, every 10 to 30 seconds, sometimes the fans would just move like a second "clock hand" it would move one second then stop, like a tick tock, but once every so offern, other times the fans would go 100% then stop, all in less than 3 seconds, as seen in the following photo :

 

 

 

 

here are my fan settings :

 

 

I did the mod, because I want the fans to last as long as possible, the nose is just a plus, I agree with everyone here, that when a gpu is doing nothing but playing videos and nothing, the fans should stay off,

[Lays]

@SignedAdam, the reason is most likely the fan curve having an angle.

 

The fan probably tries to spin up, but because it doesn't have a straight line, it tries to spin at a very low % first, the fan needs to be around ~20-35% to start up, otherwise it will continue to try and spin but doesn't have the power to start.

 

 

The easiest fix would be to make your fan curve look like this, and then just change the temperatures to whatever you want.

 

BE SURE that it goes from 0%, to 30% or higher for your first gray dot.

 

[SignedAdam]

Lays, hope i'm not being rude, but you could be wrong, I have just managed to solve my own problem,

 

The problem is TMP11 is set to 40, by default, when the card is running at the desktop, or  just playing youtube videos, "nothing high graphic" the card stays at about 40c, the temperature sensors report this information to the bios, which then puts the speed of the fans, up to 33% something ? however after it does that, some other setting tells the card it should be 0% rpm, so it gos back down, till the card gos passed or under 40c, again changing TMP11 to 60, tells the bios to only allow that to happen at 60c, which is what everyone wants it to be, it also means the card does not spin up and down its fans, i'm not getting the random spins anymore, so I believe my analysis and correction of the settings has solved my own problem

 

here's a a screen shot of the new settings everyone needs to apply,

 

 

If the photo has been delete the settings that need changing are :

 

RPM11: 0

TMP11: 60

PER01: 0

RPM01: 0

 

in basic terms, the settings that were given by you were making the card have a conflict, this problem could only be effecting the GV-N970G1, so i guess everyone with any other card should stick with Lays settings,

If you don't have auto & user define enabled, it will default to those values in the BIOS.  If you have AUTO & user defined enabled on afterburner, then it will use the curve you set.

 

In my guide, I essentially explain & say how to get rid of the limit and enable the 0% fan, I don't go into detail on how to change the card's BIOS to do it without afterburner, as most people IMHO should have some sort of monitoring software / overclocking software with these type of cards anyways.

 

 

There are two ways of doing this, the way you just said it, and the way I explain it in the video & guide.

If it wasn't working for you, it's because you didn't have AUTO fan mode enabled + user defined at the same time.

 

(This allows afterburner to override the settings in Afterburner)

[SignedAdam]

@Gofspar - you must be a Therapist or something, you are correct, Steve jobs and many other great people have my issue, does not make me ret@rded thank you

 

@Lays - perfection is key for me, i'm running two operating systems on my hardware, one of my operating systems does not support the over clocking software found on windows,  so having the BIOS sort out the fans, is better for me, however, it also has fixed the fans from coming on for 3 seconds then turning off, many other users have had this problem of random spins happening, 

[SignedAdam]

is there anyway to change the hysteresis in MaxwellBiosTweaker,

 

 

so that when it does get to almost 60C, it don't start and stop the fans again, if I could I would set TMP11 to zero, but I understand I need the fans to spin "just a little bit before hitting the 80c zone"

 

[dongus]

Hey, i followed all your instructions, have redone this like 5 times, i can set the curve in msi afterburner to 0 and on auto it sets to 0, but the minimum it will run at is %13. im running sli zotac 970s (non amp! or whatever, just the vanilla one) gpu z says it's 0% but it's not. I've tried the different nvflash program and that did nothing.

[McGinSpace]

I can confirm that this works on at least one EVGA 750ti model.

 

Now to learn to set the fan curve in Linux...

[JTM88]

I was able to get this to work on my MSI GTX 960. While I can run it completely off it bothered me seeing the temps so high at idle, even though I know it's not an issue. So I just kept raising the fan speed up to the point where I could hear it and then backed off. I think I'm running at about 25% until 65C and then it ramps up to 100% at 75c. The only time it hits these is when I'm in a game, and with my speakers I can't even hear the fan.

Hey I just finished this and I can confirm it works on my 970 G1 gaming . 

Very nice tutorial , I would say much better than the linus's interpretation of it 

 

I set my fan to 500 rpm or ~ 15 % , I don't really mind the fans spinning but the G1 has an extremely aggressive idle fan speed . I was very surprised , my gigabyte 770 ran at about 15% at idle , and considering Maxwell is cooler , I just don't get why gigabyte would do it . 

 

Anyway , one thing I have to add is , I would recommend to use ONLY the program versions you have linked . I downloaded a newer version of maxwell bios tweaker , and when trying to load the bios it gave an error . 

When I got the ones you have linked , everything worked perfectly . Now I have silence once more

Linus's interpretation was quite good, albeit came from my guide so I think mine would be.. "More complete?" I suppose.

 

I'm going to see if this works on my new 780 Lightning later I think.

[Tim89]

Hi Lays,

 

I have followed your tutorial and my Gtx 970 G1 card is much more silent, however, My fans spin randomly spin from time to time at near full speed under little gpu load, it is quite annoying.

 

Is there anyway this can be rectified - I have changed my fan curve and set my temperature hysteresis to 10 degrees (please see attached) however, the random spikes still occur.

 

Thanks

 

Tim

Later---

Well thanks for the tutorial... but for my Inno3D GTX 980 it doesn't work

Went into MSI AB and stays at 25% won't budge.

 

 

!!!!Update** Somehow its working now THANKS!!!
